“I do not live for what the world thinks of me, but for what I think of myself.”

Context: I never thought about things at all, everything changed, the distance that wedged itself between me and my happiness wasn't the world, it wasn't the bombs and burning buildings, it was me, my thinking, my cancer of never letting go, is ignorance bliss, I don't know, but it's so painful to think, and tell me, what did thinking ever do for me, to what great place did thinking ever bring me? I think and think and think, I've thought myself out of happiness one million times, but never once into it. (p. 17)

Context: !-- I was getting 8 to 10 orders [for tapes of Emacs] a month. And, if necessary, I could have lived on just that, because --> I've always lived cheaply. I live like a student, basically. And I like that, because it means that money is not telling me what to do. I can do what I think is important for me to do. It freed me to do what seemed worth doing. So make a real effort to avoid getting sucked into all the expensive lifestyle habits of typical Americans. Because if you do that, then people with the money will dictate what you do with your life. You won't be able to do what's really important to you.<!-- line 422
